Which Veronica veil? There are at least three. One held in the vatican is Linen and has no image worth calling an image:
Or another kept in Manoppello Italy the has the image of a man with a wispy beard... which is actually a self-portrait done by Raphael which has clearly visible paint pigments on it, particularly on the eyes and teeth. Raphael painted his self portrait on either Byssus, the rarest cloth on earth made from the fibers of a sea-urchin, or Cambric, a very fine French cotton used for veils, and sent it to Albrecht Dürer in response to a similar self-portrait Dürer sent to him.
If we go just by the legend of the Veronica, then the Veil predates that Shroud by at least a few hours, having supposedly been created on the Via Dolorosa just before the crucifixion and the Shroud being created a day or so after the crucifixion.

The only comparison done of two cloths by computer that showed such a degree of equivalence are the Shroud and the Sudarium of Oviedo, the sweat cloth that is supposed to have covered Jesus' face in death, where the blood stains share over 70 points of congruity. The Sudarium has a provenance that goes back to the fifth Century while the Shroud known provenance extends only back to the 14th.
Another Veronica candidate is the Holy Face of Genoa:
